First Claim
1. Apparatus for producing carbonated flavored drinks comprising means for carbonating water, concentrate supply means for supplying concentrate in predetermined quantities, and discharge means for discharging carbonated water from the carbonation means and concentrate from the supply means, said supply means comprising a housing containing a metering chamber connected to said discharge means, coupling means for coupling a concentrate container to said housing, a venturi connectable to a source of gas under pressure and in communication with said metering chamber for creating reduced pressure therein when said venturi is operated, and said coupling means having a first passage for the supply of concentrate to said metering chamber on creation of said reduced pressure and a second passage for conducting gas from said venturi into said container.

Abstract
Apparatus for making flavored carbonated beverages includes a carbonator (2) and concentrate supply (4). The latter includes a metering chamber (24) so that metered quantities of concentrate are supplied for making each drink. Concentrate is drawn from a supply bottle (6) into the metering chamber (24) by creating a reduced pressure therein with the aid of a venturi (20) through which carbon dioxide gas under pressure is supplied. The gas from the venturi (20) is directed downwardly into the upper part of the concentrate bottle which includes a baffle structure (48) which prevents this gas impinging directly on the surface of the concentrate and which is so arranged that the gas entering the bottle (6) passes to a gas outlet (72) route only via the space above the concentrate, so that unwanted discharge of concentrate through the outlet route is prevented.

9. Apparatus for producing carbonated flavoured drinks comprising means for carbonating water;
- a container containing concentrate;
concentrate supply means for supplying concentrate from said container in predetermined quantities; and
discharge means for discharging carbonated water from the carbonation means and concentrate from the supply means;said supply means comprising a housing containing a metering chamber connected to said discharge means, coupling means for coupling the concentrate container to said housing, a venturi in communication with said metering chamber for creating reduced pressure therein when said venturi is operated, and means for connecting the venturi to a source of gas under pressure to operate the venturi, said coupling means having a first passage for the supply of concentrate to said metering chamber on creation of said reduced pressure and a second passage for conducting gas from said venturi into said container; said container including in an upper portion structure defining a first route for the transfer of concentrate from the container to the metering chamber, a second route for the inlet of gas from said venturi and a third route for the exit of gas from said container, said structure being so arranged that said gas from said venturi is substantially prevented from impinging directly upon the surface of concentrate in the container and from passing directly from said gas inlet route to said gas outlet route. - View Dependent Claims (10, 11, 12, 13, 14, 17, 18, 19, 20, 21, 22, 23, 24)
